4-tert-Pentylphenol (4-tert-Amylphenol) is used to make phenolic resins (novolaks and resoles), which are used in paints and varnishes and as printing ink resins. The ethoxylated novolaks are used as oil field demulsifiers. Because of the high cost of 4-tert-pentylphenol, which is related to the high cost of the starting material, many of the resin applications have been reformulated using 4-tertbutylphenol. The substance is also used as a germicide in cleaning solutions, although it is being replaced by quaternary ammonium salts. Kegley et al. (2007) confirm that both the substance and its potassium and sodium salts are antimicrobial or fungicidal active ingredients of several disinfectant products that are currently registered with the US authorities. It appears that some of these products are used in animal husbandry, including the control of highly infectious diseases such as avian influenza (US EPA, 2007d). 4-tert-Amylphenol was used as an esterogen receptor (ER) ligand.

In Vivo Use Guide
Curator's Comment: 4-tert-pentylphenol was administered by oral gavage to pregnant Sprague-Dawley rats (25 per dose) from gestation day 6 to 15. Doses were 0, 50, 200 and 500 mg/kg/d and dams and litters were sacrificed and examined after termination of the study on gestation day 20. There was evidence of significant maternal toxicity at the top two doses; the incidence of hair loss, abnormal respiratory sounds and mucoid/soft stools were increased and body weight gain and food consumption were decreased by 10–50%. The NOAEL for repeat dose toxicity for this study was 50 mg/kg/d.
Acute oral toxicity tests have been conducted with 4-tert-pentylphenol in the rat. In the more recent study, conducted to OECD guidelines, five male and five female animals were given 4-tert-pentylphenol in corn oil by gavage at a limit dose of 2,000 mg/kg.
Route of Administration: Oral
For the agonist assay, 4-tert-Pentylphenol diluted in DMSO was added to the wells to final concentrations of 10 uM, 1 uM, 100 nM, 10 nM, 1 nM, 100 pM, and 10 pM, in quadruplicate. A stable transfected cell line, hERa/HeLa, was used.
